Pretty much as Sparky does.
Make sure that you get your back foot on the rear beam for the initial lift, this should not be too much of a struggle if the crew has lifted above head-height on the ground.
I always rig the pole and attach the spinny halyard to the end of the pole, when the crew has had the mast lifted out of their hands, he/she can come to the side of the boat and 'hoist' the spinny halyard to keep the mast going in the right direction. Once the mast is up, the halyard can be tied off after cleating [for security]. This means that you do not have to fumble with pins and rings on the forestay whilst holding the mast up.
Always remember to slacken off one of the shouds right to the top to give enough slack to easily connect the forestay.

Using the spinny halyard like this, and finding something like a trailer mast support to prop the mast up on, means that it is not very difficult to raise the mast on your own when you feel like you need to prove a point!
